php - How to trim a Base-64 encoded string? -


I'm not too much a PHP expert; I am encoding a URL with base64_encode I'm quite weird I get very long encoded strings with letters as I want. Is there no way to trim the long line of such characters, say it 10 or 15 characters, can I explain it again later?

I know that is trim () but what I really do not want is I want to have a long encoded string that I want to reduce and then decode it again Want to do

Any thoughts?

  • If you do an encoded physically small If you want, it is not possible to "shorten any string".

    String (with only the end result is only a part of that string), apply not to substr () on the encoded version: decoding it first

  • Another option is minimize it is string it may be Reduce to some extent: Your benefits may vary depending on it, however: Compression rate will depend on which type of work you have The data with little input string, the result may be even larger than the original.

  • If you want to reuse a variable in a multi-page process , and do not transport it through any link or form Wish, consider creating a short random key and archive data in user session: 

      $ _ session [$ random] = "lllloooooooooooong data here";

    You can pass on a random key, and always access "long" data using the $ _ session [$ randomKey] . You must be the beginning for this.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
